iOS: Device orientation on load

Question

It seems that when my app loads, it does not know its current orientation:

UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
if (o         


        

Answer 1

for those who looking answer for Swift 3 or 4. just add that code inside of viewDidLoad() block.

let orientation = UIApplication.shared.statusBarOrientation
if orientation == .portrait {
      // portrait   
} else if orientation == .landscapeRight || orientation == .landscapeLeft{
      // landscape     
}

update for depreciation alerts for IOS 13 and Swift 5.x use code block below.

 if #available(iOS 13.0, *) {
        let orientation = UIApplication.shared.windows.first?.windowScene?.interfaceOrientation
        if orientation == .portrait {
                     // portrait

               } else if orientation == .landscapeRight || orientation == .landscapeLeft{
                     // landscape
               }
    } else {
        // Fallback on earlier versions
        let orientation = UIApplication.shared.statusBarOrientation
        if orientation == .portrait {
                            // portrait

    } else if orientation == .landscapeRight || orientation == .landscapeLeft{
                               // landscape
    }
    }
